Be it known Lthat I, CHARLES E. CIAsE, of Xenia, in the county of Greene, in the State -of Ohio,'h'ave invented a new Cupfor the Protection of the Inner Surfaces of Superhenting-Steam Boilers; and I do further l declare thatthe following is a full and exact description thereof, reference being had tothe accompanying drawings, and to the letters of reference 'marked thereon'. l i The nature of my invention consists in the construction ofV a. metal cup, which extends upwardfrom the i lower and inner surface of the boiler suiciently far to receive all of the walter or steam which is thrown in from the feed-pump of the engine,l thus preventing the sudden cooling or crackingroi" the boiler. Y To enable others skilledin theart to make and `use my-inven'tion, Iwill proceed to describe its construction and operation. l' i v 4 g' 'i I construct my cup, as represented in the accompanying drawings, of metah'n'nd having experimented and tested all the metals, I find copper to be `the bestA for this use. G represents the cup, which rests 'upon or is attached to the bottom of theboiler bythe short legs H, which, elevating 'the cup, allow the steam generated in the boiler to circulate freely on all s'ideslof it. This cup extends upward far enough to screenthe boiler from the jets of water thrown into the boiler through the coiled pipe or pipes B, and above theline of the sprinkler C. The cup is madein size to be alittle less than the inner diameter of the boiler, thus, by its nearness to the heated surface of the boilerreceiving`ith`e heat therefrom, and converting' the water or steam into superheated steam as fast as it comes in contact with the cup. A

What I claim as new, and desire to secure by Letters Patent, is- The metal cup Gr, constructed and arranged substantially upon the principle nd'in the manner herein set forth.

CHARLES E. CASE.
